The NOVELTY study is a multi-country, multicentre, observational, prospective, longitudinal cohort study which will include patients with a physician diagnosis, or suspected diagnosis, of asthma and/or COPD. Patients will undergo clinical assessments and receive standard medical care as determined by the treating physician. All patients enrolled in the NOVELTY study will be followed up yearly by their treating physician for a total duration of three years. In addition, patients are expected to be followed up remotely once every quarter.
